IMPROVEMENT IN APPARATUS FOR ROLLING METAL.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom it may concern:

Be it known that we, CHARLES WHILE, WILLIAM LEWIS, THOMAS STRICKLAND,and SAMUEL OAnDIcK,

. of Spuyten Duyvil, in the county of Westchester and a full, clear, andexact description thereof, which will enable others skilled in the artto make and use the same, reference being bad to the accompanyingdrawing forming part of this specification.

The object of this invention is improvement in machines for reducingiron and consists in the construction and arrangement hereinafter setforth.

In the accompanying drawing- Figure l is a front view.

Figure 2 is a top or plan view.

Figure 3 is a cross-section of fig. 2 on theline-a; m.

Figure 4 is a plan view of the rolls.

Similar letters of reference indicate corresponding parts.

A, B, and 0 represent the conical rolls.

D E are the heads of the revolving frame, in which the rolls areconfined.

F represents bars or rods, by which the heads are connected together.

The smaller ends of the rolls are confined in a recess in the head E,where theyare kept in proper position by suitable boxes.

The journals on their other ends are confined on the head D by box-capsin the ordinary manner of securing journals. 1

Gr represents bevel-wheels on the ends of the journals I, (see fig. 4,)which journals extend through their boxes and mesh into a bevel-wheel,H, seen in dotted lines in fig. 1.

This bevel-wheel H is placed on a hollow journal which is supported bythe stand J.

The journal is a neck or extension on the head D and forms the mouth ofthe machine, into which the -'-iron or other article to be operated uponis introduced.

This tubular journal gives access to the orifice between the rolls,which, as before stated, in shape approaches a triangle in itscross-section.

K is a gear-wheel on this tubular journal, between the stand andbevel-wheel H.

The wheel K is revolved directly from the drivingwheel L. M

M is the driving-shaft, supported by stands N and O on the bed P.

On the the other end of the driving-shaft there is anotherdriving-wheel, R, which engages with a wheel, S, on the extended hollowjournal of the head E.

It will be seen that power is applied at each end of the revolvingframe, while, by the engagement of the bevel-wheels G on the rolls withthe bevel-wheel H, each of the rolls is revolved on its own axissimultaneously with the frame and in the same direction, but at areduced speed. Revolving the rolls and the frame in the same directionserves to counteract the revolving motion imparted by the rolls to'theiron in manufacturing long bars. The rolls being placed obliquely witheach other their action upon the iron is not only to squeeze and crush,but to draw or elongate, and thus reduce the iron to the proper ordesired form.

The rolls may be made adjustable at oneor both ends by means of screws,as seen in the drawing at U, or in any other suitable manner.

The material to be operated upon is fed into the machine through thehollow journal, as seen at T, where it-is caught by the rolls andgradually worked forward until it is forced out through the other hollowjournal in a finished state.

Any malleable material which thus passes through becomes cylindrical inform.

Having thus described our invention,

\Ve claim as new and desire to secure by Letters Witnesses: SAMUELOADDIOK,
